Violent black holes spit neutrinos at Earth and we finally caught one

Neutrinos are some of the weirdest and most mysterious particles in the universe, but we are starting to learn more about their origins. For the first time, a team of researchers has traced a single high-energy neutrino back to its birthplace, a supermassive black hole around 4 billion light years away.

On 22 September last year, a blue light pulsed through the ice deep under the South Pole. This light was generated by a high-energy neutrino passing through Earth and picked up by an experiment called the IceCube detector that traced the …
